## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "so_xref_string",
    "arguments": {}
  }
}
```

## Why so_xref_string is rated Low

This is a read-only analysis tool. It searches and retrieves cross-reference data from native Android libraries, similar to debugger/decompiler queries (IDA Pro reference indicates static analysis). No code execution, data modification, or destructive operations occur. The low severity reflects that misuse would only expose code structure and strings already present in the binary, not cause external damage.

From the tool's own definition: "Tool name and description indicate it 'finds string cross-references' and 'returns function context' (IDA-level functionality)."

## Use case

AI agents call so_xref_string to retrieve information from SO Analyzer MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches SO Analyzer MCP:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "so_xref_string": {}
  }
}
```
